I haven't had the Cohiba, but I have had both the Partagas Club and the Montecristo Mini, which are the same size/packaging.
I can tell you that they're really cigarette-like, as far as the size goes, and they burn REALLY HOT and REALLY QUICK...like, not quite as fast as a 3-minute cigarette, but probably around 8 to 10 minutes.
Also, I don't know if it's because of freshness or the vitola or what, but the ones I've smoked have been shockingly acidic....and not in the good way, like "all Cuban tobacco is somewhat acidic" but rather in the bad way of "this kinda burns my tongue and lips the way I imagine hydrochloric acid would do".
YMMV
